I'm not a pediatric coder and not really familiar with this. Our program integrity unit is questioning paying claims when a diagnosis with a "N" edit is submitted when the age of the patient is over 29 days. They state this edit indicates the age of the patient must be < 30 days old. Is that correct and if so, where is that documented? When I read the edit it sounds like it can be used as long as the patient is not a year old yet. Any help will be appreciated.
